[Icom] Restrictive Audio Icom IC-901A/2400A

[Steve C Walko]

Hello group,

    I noticed that my Icom IC-901 suffers from restrictive audio that is 
mostly high ended with no lows.  My older Icom rigs did not have audio 
filtering and I had much better sound.  Has anyone modified their 901A or 
2400A to receive more lows in the audio?  Perhaps someone has a schematic 
they'd like to share that might show the capacitor that needs to be changed 
to receive fuller audio.

Thanks in advance,
Steve
